Add article description

The Sutter Basin is a 264 sq mi (680 km2)[1] area of the Sacramento Valley in the U.S. state of California, and is part of the Feather River drainage basin. The basin includes the Sutter Basin Fire Protection District of ~127 sq mi (330 km2)[2] and uses irrigation from the Thermalito Afterbay's Sutter-Butte Canal.[3] The Feather River and the Sutter By-Pass are the basin's east and southwest borders.

The Sutter Bypass is a leveed channel of the Lower Sacramento Valley Flood-Control System along the southwest portion of the Sutter Basin.[4] The bypass allows channeling of escapement flow from the Tisdale Weir near the Sutter Buttes to the Feather River at 38.885421°N 121.614532°W / 38.885421; -121.614532. During Sacramento River flows of >23,000 cu ft/s (650 m3/s), Sacramento overflow tops the 53 ft (16 m) Tisdale Weir[5] and flows via the Sutter Bypass[6][7] to Feather River mile 7[8]: 3–55  (the west levee of the bypass continues along the Feather River to the Sacramento River).[9]

The bypass also receives similar Sacramento escapement flow from the Colusa Weir,[9] and the Snake River, Gilsizer Slough, Wadsworth Canal, and other west side watercourses of the Lower Feather Watershed also drain to the Feather River via the Sutter Bypass,[10] The bypass includes 3.24 sq mi (8.4 km2) of the Sutter National Wildlife Refuge,[11] which is part of California's ~5.00 sq mi (12.9 km2) Sutter Bypass Wildlife Area.[12]
